Pheno Journal Club: ‘Bubble velocities in local equilibrium from a pseudopotential’

Gray Room 3 Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs

Speaker: Eric Madge, IFT Venue&Time: 12:00 / Grey room 3 Abstract: We present a new method to estimate terminal bubble velocities during first-order phase transitions in a plasma in local equilibrium. The method relies on calculating the extrema of a modified potential function for the scalar field undergoing the transition. The shape of this function, […]

Seminar: ‘Dark Sector Karaoke: A 3D EFT for a Pitch-Perfect Phase Transition’

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Scientific activities

Speaker: Cristina Puchades Ibáñez (University of Mainz) Venue & Time: Red Room / 15:00 Abstract: We explore the dynamics of cosmological phase transitions in a dark sector model featuring a dark photon associated with a U(1)D gauge symmetry and radiative symmetry breaking. Our analysis focuses on different approaches to construct the effective potential: the high-temperature […]

SPS Journal Club: ‘K-Points and Type IIB/Heterotic Duality with NS5-Branes’

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs

Speaker: Lorenzo Paoloni (IFT) Venue & Time: Red Room / 12:00 Abstract: We revisit type II_0 limits in the vector multiplet moduli space of compactifications of Type IIB string theory on Calabi-Yau threefolds. These limits are special because they cannot be described using mirror symmetry. While we showed in previous work that the gravitational duality […]

Seminar: ‘Reviving PBHs: primordial black holes from supercooled phase transitions revisited’

Scientific activities

Speaker: Piotr Toczek (Warsaw University) Venue & Time: 15:00 / Red Room Abstract: Primordial black holes, hypothetical objects that may have formed in the early Universe through the interplay between high-energy physics and gravity, are very appealing candidates for dark matter. In this seminar, I will discuss their formation as a result of the collapse of […]

Old Journal Club: ‘Particle Spectrum in Quantum Field Theory’

Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Journal clubs

Alejandro Puga (IFT) will present "Particle Spectrum in Quantum Field Theory" de Alexander M. Polyakov (JETP Lett. 20 (1974) 194-195) Abstract: We investigate the nonperturbative structure of quantum field theories and its consequences for the physical spectrum of excitations. Emphasis is placed on the role of instantons—topologically nontrivial field configurations—which contribute essentially to tunneling processes and […]

Polygonal Gravity Seminars

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

Scientific activities

Madrid's Polygonal Gravity Seminar Series Wednesday, January 29th. Blue Room (IFT) 11:30h First talk Speaker: Robie Hennigar (U. Durham, UK) Title: Building Regular Black Holes Abstract: The study of regular (singularity-free) black holes has a long history, but progress has been limited by the absence of a dynamical framework in which they form and by […]
